Be it known/hat ,LfRronAnn B'AER, a citizen of Czecho- Slovakia, and resident of the borough of Manhattan, in the city, county, and Stateiof New York, have invented certain new? and; useful ,I mprovements in PermutationaLocks, of which the following is a description. I, l

.The present inventionrelates to improve,- ments in permutation locks, and has'for its object to provideaiook adapted for use upon ordinary house doorsor the-like, and which .may be operated with vfacility by one knowing the combinationof the same. -I further proposetoprovidea novel type ofkey adaptedto cooperate with the look to bring the several parts, thereof into proper relation to, permit opening of the door so that theinvention provides at onoea lock which may be opened by a key,qa nd may also be opened-without a key, and: by

familiar .with the combination. 9 L A further object is toprovide lock be readily operated -;from one side of the door ,fwi thoutthe manipulation automatically lockitself when the, door is Other objeotsjareto provide .alock which will not readily get out of order, whichwill be simple and :economic al in construction, and practicable for house door use. It-is e; changing of With these and] other objects in view, em-

' bodiments of invention are shown in the 1accompanying' drawings, and these embodi- "-ments'; will be -hereinafter more fully described with reference: thereto,

and the invention will be finallypointed "out. in the I claims.

provided with a corresponding shaped cutout, as shown in'Figs. 6 and 7 andiupon the shank relatively near its outer end there is provided a lug. 64 adaptedtoengagea cutout65in the end of the-sleeve 28,]so disposed as tobrin g' the disk 30 into suchz p'osition that its cut out'po'rtion 44 is in alinement with l the cut-out '20 when the shank of the key isyinterlooked v'vithfv the shaft, and the lug 64 is engaged' with said cut-out.
